## Overview

The Gator Cases Voltage Doubler Adapter Cable (GTR-PWR-2XVOLTAGE) combines two 9V or 18V power supply outputs into one higher voltage output (up to 24V) using dual 2.1mm barrel plugs. Its bright yellow design ensures easy identification, while maintaining current stability to safely power effects pedals requiring higher voltage. Ideal for professional musicians seeking reliable, high-performance power solutions.

## Description

The voltage doubler adapter cable by Gator Cases allows you to power up effects pedals that require higher voltage to operate. The GTR-PWR-2XVOLTAGE works by combining the voltage from two (2) outputs on a power supply to yield a higher total voltage rating from one (1) power output. The voltage doubler will turn two 9V outputs into one 18V output, or two 18V outputs into one 24V output. While the voltage is increased, the current remains the same.
